PromptBase is a marketplace where creators sell ready-made prompts for popular AI models. Instead of guessing wording from scratch, you browse a category, preview sample outputs, and buy a prompt that already produces a specific style or effect in tools like Midjourney, DALL-E, Stable Diffusion and ChatGPT.
Thousands of ready-to-use prompts organised by model and by output type, from illustration styles to marketing copy.
Listings are grouped by the model they were built for, so you can filter to the tool you actually use.
Each prompt is shown with example outputs, making it easy to judge the style before spending anything.
Anyone can upload prompts for sale and earn revenue share on every copy sold.
